Application September 15, 1939, Serial No. 295,136 15 Claims (01. 16 86)I I L of resilient material such as rubber or rubber This, inventionrelatesgenerally to door checks,"

1. e., devices forjlimiting the swinging movement of doors, and refersmore particularly to door checks of the concealed type.

One of the essential. objects} of the invention is to provide a doorcheck wherein provision is made for effectively absorbing or cushioningshocks resulting from checking the swinging movements of the doors.

Another object is to provide a strong and du rable door check that issimple in construction, economical to manufacture, and easy to install.

Other objects,.advantages and novel details of construction of thisinvention will be made more apparent as this description proceeds,especially when considered in connection with the accompanying drawing,wherein: t

Figure 1. is a fragmentaryhorizontal sectional view through a swingingdoor supporting, hinge pillar therefor, and door check embodyingrnyinvention, and showing the arrangement of parts when the door is inclosed position;

Figure 2 is a view similar to Figure 1, but showing' the door in openposition;

Figure '10 is an end view of thedoor checkillus- .trated in Figures 8and 9.

Referring now to the drawing, A is the head, B is the shank, and C isthe shock absorbing or cushioning element of a door check embodying myinvention. As shown, the head A and shank B are formed from one piece ofrelatively heavy spring wire and cooperate to hold the cushioningelement C. Preferably the head A comprises the laterally bent endportions l and 2 of the wire, while the shank B comprises the. elongatedI9 turn-bent portions 3 and 4, respectively, of the Wire. Thereturn-bend of the wireis preferably opened slightly to provide an eye 5for the reception of a suitable anchorage member such 'asB. Thecushioning element 'Q'is preferably a block a slightly modifiedcomposition and is sleeved upon the shank B ad- 'jacent the head A. Inthis construction a washer D is also-sleeved on the shank B between thecushioning element C and head A and serves as a tieor coupling betweenthe return-bent portions 3 and 4 of the Wire at the free ends of thelatter. As shown the washer D has a central slot I of sufficient lengthto receivethe eye 5 when the washer is sleeved upon the shank and isprovided in opposite edges of said slot with notchest and 9 forreceiving the shank portions 3 and 4 of thewire. Preferably the slot 1and notches B and 9 are so formed that the washer D may be turned 90 onthe shank B from the In use the door check extends substantiallyhori'zontally between the door E andits supporting hinge pillar F. As.shown, the anchorage member 6 is in-itheform of a pin and is carried bytwo spaced angle plates ID, fixed to the door E. The hingepillar F ishollow and is provided in one wall I l thereof with a slot l2 forreceiving the shank B of the door check. Thecushioning element C, washerD, and head A are located within the hollow pillar so that thecushioning element C is engageable with thewall II to limit the outwardswinging movement of the door when the-latter is opened. However; it isapparent that the arrangement just described may be reversed, i. e., theanchorage memberfi may be secured to the hinge pillar F and the, door E.may be apertured to receive the shank B. In either instancethe door Ewould be yieldably checked when opened. I

In Figures 5, 6 and '7 I have illustrated a slight modification in whichthe washer D isprovided upon opposite sides of the slot 1 with two holeshead A itself sufiices. Actually the 'S-shape of the head is such thatadded spring action to the cushioning element C is aiforded.

In each instance where wire is used it is to be understood that the wireis tempered spring steel.

Thus, from the foregoing it will be apparent that the door checks shownand described herein are simple yet strong and durable in constructionand can be manufactured at a comparatively low cost. It also will beapparent that each form shown includes means for effectively cushioningor absorbing shocks resulting from checking the swinging movements areapplied.
